I want to call a SignalR event from Postman, I have gone through this question as well, But it's not helping me.
It's giving the below error, I have mentioned the URL as myUrl due to security reasons in this example.
Below is the C# equivalent code for the same.
private HubConnection hub connection;
private IHubProxy hubProxy;
hubConnection = new HubConnection(myUrl, useDefaultUrl: false);
hubConnection.TransportConnectTimeout = new TimeSpan(10000);
hubConnection.Credentials = CredentialCache.DefaultCredentials;
hubConnection.Closed += _hubConnection_Closed;
hubConnection.Error += _hubConnection_Error;
hubProxy = hubConnection.CreateHubProxy(myHubName);
hubProxy.On<CurrencyPair>("getItems", value =>
{
DoSomething(value);
}
Postman version 9.31.9

I have two applications that are using WS Federation and I am working to migrate one of these applications over to .NET Core. These two applications need to be able to share cookies and this is where I am running into an issue on the .NET Core side.
This is a portion of my Startup.cs
services.AddIdentity<ApplicationUser, ApplicationRole>()
.AddEntityFrameworkStores<Context>()
.AddDefaultTokenProviders();
services.ConfigureApplicationCookie(options =>
{
options.LoginPath = new PathString("/Account/Login");
//LOGIN WORKS CORRECTLY WITH THE BELOW LINE COMMENTED
options.TicketDataFormat = new AuthTicketDataFormat();
options.Cookie.Name = "cookiename";
options.Cookie.Path = "/";
options.Cookie.Domain = "";
});
services.ConfigureExternalCookie(options => {
options.LoginPath = new PathString("/Account/Login");
//LOGIN WORKS CORRECTLY WITH THE BELOW LINE COMMENTED
options.TicketDataFormat = new AuthTicketDataFormat();
options.Cookie.Name = "cookiename";
options.Cookie.Path = "/";
options.Cookie.Domain = "";
});
services.AddAuthentication()
.AddWsFederation(options => {
// MetadataAddress represents the Active Directory instance used to authenticate users.
options.MetadataAddress = authentication.GetValue<string>("AdfsWsFedMetadataUri");
// Wtrealm is the app's identifier in the Active Directory instance.
// For ADFS, use the relying party's identifier, its WS-Federation Passive protocol URL:
options.Wtrealm = authentication.GetValue<string>("AdfsRelyingPartyIdentifier");
});
I am able to see that I do receive a cookie in the Network tab, but the issue I am having is that I am being put into an infinite loop because on my anonymous Callback endpoint I have the following:
var loginInfo = await this._signInManager.GetExternalLoginInfoAsync();
//loginInfo is always coming back as null
if (loginInfo == null) {
return RedirectToAction("Login");
}
It seems the issue is being caused by options.TicketDataFormat and creating a custom format for the cookie. The cookie seems to be created correctly with the ticketDataFormat, but getExternalLoginInfoAsync on signInManager is always returning null.
Any help or direction is greatly appreciated as I've been banging my head against the wall for a day trying to figure this out.
I am having some problems attempting to post to an API gateway endpoint.
On my API gateway I have my gateway all set up, and tested via the tool and am getting results and can verify that the step function is in fact executing the request appropriately.
{
"executionArn": "arn:aws:states:us-east-2:xxxxxxxxxxxx:execution:DevStateMachine-XXXXXXXXXXX:c9047982-e7f8-4b72-98d3-281db0eb4c30",
"startDate": 1531170720.489
}
I have set up a Stage for this for my dev environment and all looks good there as well. where I am given a URL to post against.
https://xxxxxxxxxx.execute-api.us-east-2.amazonaws.com/dev/assignments
In my c# code I have the web client defined as follows:
public Guid QueueAssignment(AssignmentDTO assignment)
{
using (var client = new HttpClient())
{
var data = JsonConvert.SerializeObject(assignment);
var content = new StringContent(data);
var uri = "https://xxxxxxxxxx.execute-api.us-east-2.amazonaws.com/dev/assignments"
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var response = client.PostAsync(uri, content).Result;
if (response.IsSuccessStatusCode)
{
_logger.Info("Successfully posted to AWS Step Function");
_logger.Info(response);
}
else
_logger.Error("Error posting to AWS Step Function");
_logger.Error(response);
}
}
Everytime this post is attempted I get the following error:
System.Net.WebException: The remote name could not be resolved: 'https://xxxxxxxxxx.execute-api.us-east-2.amazonaws.com'
Is there something I am missing in posting to this URI or some type of conversion I need to do? Im kind of at a loss on where to go on this on.
Identity server is implemented and working well. Google login is working and is returning several claims including email.
Facebook login is working, and my app is live and requests email permissions when a new user logs in.
The problem is that I can't get the email back from the oauth endpoint and I can't seem to find the access_token to manually request user information. All I have is a "code" returned from the facebook login endpoint.
Here's the IdentityServer setup.
var fb = new FacebookAuthenticationOptions
{
AuthenticationType = "Facebook",
SignInAsAuthenticationType = signInAsType,
AppId = ConfigurationManager.AppSettings["Facebook:AppId"],
AppSecret = ConfigurationManager.AppSettings["Facebook:AppSecret"]
};
fb.Scope.Add("email");
app.UseFacebookAuthentication(fb);
Then of course I've customized the AuthenticateLocalAsync method, but the claims I'm receiving only include name. No email claim.
Digging through the source code for identity server, I realized that there are some claims things happening to transform facebook claims, so I extended that class to debug into it and see if it was stripping out any claims, which it's not.
I also watched the http calls with fiddler, and I only see the following (apologies as code formatting doesn't work very good on urls. I tried to format the querystring params one their own lines but it didn't take)
(facebook.com)
/dialog/oauth

&logger_id=xxx
&hash=xxx

/id/signin-facebook
?code=xxx
&state=xxx
I saw the code parameter on that last call and thought that maybe I could use the code there to get the access_token from the facebook API https://developers.facebook.com/docs/facebook-login/manually-build-a-login-flow
However when I tried that I get a message from the API telling me the code has already been used.
I also tried to change the UserInformationEndpoint to the FacebookAuthenticationOptions to force it to ask for the email by appending ?fields=email to the end of the default endpoint location, but that causes identity server to spit out the error "There was an error logging into the external provider. The error message is: access_denied".
I might be able to fix this all if I can change the middleware to send the request with response_type=id_token but I can't figure out how to do that or how to extract that access token when it gets returned in the first place to be able to use the Facebook C# sdk.
So I guess any help or direction at all would be awesome. I've spent countless hours researching and trying to solve the problem. All I need to do is get the email address of the logged-in user via IdentityServer3. Doesn't sound so hard and yet I'm stuck.
I finally figured this out. The answer has something to do with Mitra's comments although neither of those answers quite seemed to fit the bill, so I'm putting another one here. First, you need to request the access_token, not code (authorization code) from Facebook's Authentication endpoint. To do that, set it up like this
var fb = new FacebookAuthenticationOptions
{
AuthenticationType = "Facebook",
SignInAsAuthenticationType = signInAsType,
AppId = ConfigurationManager.AppSettings["Facebook:AppId"],
AppSecret = ConfigurationManager.AppSettings["Facebook:AppSecret"],
Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = (context) =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("urn:facebook:access_token", context.AccessToken, ClaimValueTypes.String, "Facebook"));
return Task.FromResult(0);
}
}
};
fb.Scope.Add("email");
app.UseFacebookAuthentication(fb);
Then, you need to catch the response once it's logged in. I'm using the following file from the IdentityServer3 Samples Repository, which overrides (read, provides functionality) for the methods necessary to log a user in from external sites. From this response, I'm using the C# Facebook SDK with the newly returned access_token claim in the ExternalAuthenticationContext to request the fields I need and add them to the list of claims. Then I can use that information to create/log in the user.
public override async Task AuthenticateExternalAsync(ExternalAuthenticationContext ctx)
{
var externalUser = ctx.ExternalIdentity;
var claimsList = ctx.ExternalIdentity.Claims.ToList();
if (externalUser.Provider == "Facebook")
{
var extraClaims = GetAdditionalFacebookClaims(externalUser.Claims.First(claim => claim.Type == "urn:facebook:access_token"));
claimsList.Add(new Claim("email", extraClaims.First(k => k.Key == "email").Value.ToString()));
claimsList.Add(new Claim("given_name", extraClaims.First(k => k.Key == "first_name").Value.ToString()));
claimsList.Add(new Claim("family_name", extraClaims.First(k => k.Key == "last_name").Value.ToString()));
}
if (externalUser == null)
{
throw new ArgumentNullException("externalUser");
}
var user = await userManager.FindAsync(new Microsoft.AspNet.Identity.UserLoginInfo(externalUser.Provider, externalUser.ProviderId));
if (user == null)
{
ctx.AuthenticateResult = await ProcessNewExternalAccountAsync(externalUser.Provider, externalUser.ProviderId, claimsList);
}
else
{
ctx.AuthenticateResult = await ProcessExistingExternalAccountAsync(user.Id, externalUser.Provider, externalUser.ProviderId, claimsList);
}
}
And that's it! If you have any suggestions for simplifying this process, please let me know. I was going to modify this code to do perform the call to the API from FacebookAuthenticationOptions, but the Events property no longer exists apparently.
Edit: the GetAdditionalFacebookClaims method is simply a method that creates a new FacebookClient given the access token that was pulled out and queries the Facebook API for the other user claims you need. For example, my method looks like this:
protected static JsonObject GetAdditionalFacebookClaims(Claim accessToken)
{
var fb = new FacebookClient(accessToken.Value);
return fb.Get("me", new {fields = new[] {"email", "first_name", "last_name"}}) as JsonObject;
}
Please ignore the spelling mistake, I cannot copy code so I have typed the whole thing and changed name of controller and method.
WEB API 2
Controller:
// Controller name is Test
public HttpResponseMessage Method1(int param1) // Post method
{
// return string
}
If I create an object of controller in test case then it is working fine. But if I want to test in localhost using following code:
Unit Test:
public void Method1Test()
{
HttpResponseMessage response;
HttpConfiguration config = new HttpConfiguration();
config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}");
HttpServer server = new HttpServer(config);
using(var client = new HttpClient(server))
{
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "http://localhost:5022/api/test?param1=1");
request.Content = new ObjectContent<int>(param1, new JsonMediaTypeFormatter());
response = client.SendAsync(request, CancellationToken.None).Result;
};
Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);
}
Now, my test case is failing. I used the same code in different project and it worked. May be it is the way I am trying to call Post method. Is this the right way to call post method with Int parameter in URL?
In help page, under API column it shows:
POST api/test/param1={param1}
Also I have put some stop point in actual service I am cursor is not stopping at that point. Why?
If I want to call the same service from browser, what URL should I pass? Is it -
http://localhost:5022/api/test?param1=1
Or something else?
I figured it out. Following is the correct unit test method but this has some extra information which I have not provided earlier i.e., passing object as an input for the service.
private void Method1Test(ObjectClass obj)
{
HttpResponseMessage response = null;
HttpConfiguration config = new HttpConfiguration();
config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}");
HttpServer server = new HttpServer(config);
using (var client = new HttpClient(server))
{
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "http://localhost:5022/api/test/1");
request.Content = new ObjectContent<ObjectClass>(obj, new JsonMediaTypeFormatter());
response = client.SendAsync(request, CancellationToken.None).Result;
};
Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);
}
So the correct URL that I was looking for was
http://localhost:5022/api/test/1
Sorry, It took long to post this answer. This method is working like a charm for more then 2 years.
im trying to write a UnitTest for a WebAPI and EF
Im trying to add Data do the database in den TestInitialize, but it didnt work. When i do the same command in a Console Applications, it works.
Is there a different in calling that webapi for tests?
[TestInitialize]
public void CreateEntityObjects()
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost:60609/");
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
Department dep1 = new Department() { Id = Guid.NewGuid(), Name = "IT" };
client.PostAsJsonAsync("api/Department", dep1);
}
Edit:
So i still just do the initialize no cleanup (later). I was looking manually if there is some data in the database. But no data, no Error, nothing.
You may try looking at the result property of the request:
var response = client.PostAsJsonAsync("api/Department", dep1).Result;
and then look at what does the server return:
string responseContent = response.Result.Content.ReadAsStringAsync().Result;
Now analyze the responseContent variable to see what possible error message you might have gotten from the server. Also you probably want to self-host your Web API in the unit test before sending an HTTP request to it, otherwise your API might not even be started.
